Hi!
I was messing around the other day and found this beautiful app called Advanced Mac Cleaner. It's clearly spam, and in the binary it suggests that the number +1 (800) 816-4424 is called. A few members of a group I'm in called it and they got the generic "pls tel information 4 activat".
On the "Web Payment Page" for the application, another number is referenced: +1 (800) 809-4806
Enjoy 🎉
